A Torch Height Controller helps improve plasma cut quality and can save a CNC Machine from crashing. This design doesn't require you to know electronics or need any custom circuits... Its plug and play! This is a COMPLETELY standalone controller with a built-in Driver powerful enough to run just about any stepper motor. (maybe a little to powerful for a NEMA17)

Need to build a machine that accurately positions objects for processing by a computer vision algorithm? Here is an example of a machine that does that for a ball trajectory application. The black anodized V-rails work well for applications in optics and imaging where the machine needs to stay out of the limelight.
